Measurement pre-test

This was by far the hardest pre-test we have taken this year I knew maybe 3 of the questions and honestly I probably got them wrong. I had no idea how to figure out a lot of the questions and I am interested to learn about some of these new things such as "significant figures" I feel that this unit will be very mathematical and interesting.
